The DB4 will probably work. It's not nominally designed for channels 7-13, but most of the channels in that band available to you are very strong. It might not have enough gain for reliable reception...

Note that the ABC station is the weakest VHF channel you are looking for. The "rabbit ears" part of the C2V is what is sensitive to that channel. Have you tried adjusting just that part of the...

One thing first - unplugging a preamp turns it into an attenuator, that is it will block signal instead of amplifying. To really test a "without amp" setup, the preamp must be completely removed from...

Boo on the Terk antenna. The absolute last thing you need is an amplifier of any sort. We have recommended the RCA antenna to many people, and it is functionally the same as the HD7000R except for...

Go back to my recommendations to you. You need an antenna like a Winegard HD7696P or similar at 25 feet for those stations. You can only bank on the VHFs from Mt....
